Re: Unresolved external symbol in a DLL

Side note: Do not use raw __declspec (dllexport/dllimport)
attributes. Use a macro instead:

#if defined(MY_DLL)
# define FOO_API __declspec (dllexport)
#elde
# define FOO_API __declspec (dllimport)
#endif

Then define MY_DLL symbol for the DLL project only. Now you can
use this macro in headers:

class FOO_API CFoo
{
....
};


You declared an instance of CFoo with name `foo' but you didn't
define it anywhere. You need to provide a definition of `foo' in
one of CPP files. Alternatively, just use CFoo class as usual:

int main()
{
    CFoo foo;

    int i = foo.foo1();
    i = foo.foo2();

    return 0;
}
